Unfortunately this is not an issue that can just be reset. No real troubleshooting is needed based on your symptoms . unfortunately this is a well known problem for this particular refrigerator and you won't see any signs of failure but the problem is the high voltage control board on the back of the refrigerator behind the 8? x 8? access panel. if you pull the refrigerator out, there is a panel on the back and if you remove it that board behind that panel test it but most likely needs to be replaced.
